Yuav Ua Li Cas Ntsuam Xyuas Cov Purity Ntawm Graphite Powder

Graphite hmoov purityyog ib qho tseem ceeb tshaj plaws tsis zoo rau ob qho tib si graphite manufacturers thiab cov neeg siv kawg. Nws cuam tshuam ncaj qha rau cov khoom lag luam thiab txiav txim siab seb cov graphite hmoov puas haum rau cov ntawv thov xws lirefractories, lubrication, roj teeb, coatings, thiab cov khoom siv siab heev.

Graphite yog ib txwm tshwm sim crystalline daim ntawv ntawm carbon. Yog li ntawd,ruaj cov ntsiab lus carbonyog dav lees paub tias yog thawj qhov taw qhia ntawm graphite hmoov purity. Ua ntej ua zaub mov xa tuaj lossis ua haujlwm ntxiv, graphite hmoov yuav tsum tau ua ntau yam kev ntsuam xyuas zoo, ntawm cov uasKev kuaj purity yog qhov tseem ceeb.

Graphite Powder Purity txhais li cas?

Graphite hmoov purity hais txog qhovfeem pua ​​ntawm taag carbonhauv cov khoom. Txij li thaum graphite muaj tshuaj lom neeg ruaj khov zoo ntawm chav tsev kub, nws cov ntsiab lus carbonntsuas tsis tau ncaj qha. Hloov chaw, purity yog txiav txim tsis ncaj los ntawmsiab -cov txheej txheem ntsuas kub.

Thaum kub siab, carbon hauv graphite yog oxidized rau carbon dioxide (CO₂) thiab volatilizes. Los ntawm kev ntsuasvolatile teeb meem thiab cov hmoov tshauv, cov ntsiab lus carbon taag tuaj yeem xam tau.

Formula rau Graphite Powder Purity Calculation

Cov qauv kev suav cov qauv yog:

Fixed Carbon (%)=100% - Tshauv (%) − Volatile Matter (%)

Cov mis no yog siv dav hauv graphite zoo tswj thiab cov qauv ntsuas thoob ntiaj teb.

Standard Test Method rau Graphite Powder Purity

Cov txheej txheem kuaj mob raug kuaj rau graphite hmoov purity yog raws li hauv qab no:

1. Kev npaj ua qauv

Ua kom hnyavob graphite hmoov kuaj, cwb1.0 g, siv ib qho kev ntsuas hluav taws xob.

Muab ib qho piv txwv rau hauv aob -lidded ceramic cruciblethiab lwm yam hauv agraphite nkoj, ob leeg nrog paub tare luj.

2. Qhuav

Qhuav ob cov qauv hauv qhov cub ntawm105 degreemus txog qhov hnyav tas li.

Sau cov luj liG1thiabG2.

3. Kev txiav txim siab tsis zoo

Muab cov ceramic crucible uas muaj graphite hmoov rau hauv asiab -kub qhov cub.

Kub ntawm950℃rau 7 feebTom qab ntawd tshem tawm thiab txias rau chav tsev kub hauv lub desiccator.

Sau qhov hnyav ntxiv liG3.

Cov ntsiab lus tsis hloov pauv yog xam raws li:
V (%) = (G1 − G3) / G1 × 100%

4. Kev txiav txim siab cov ntsiab lus tshauv

Muab lub nkoj graphite nrog graphite hmoov rau hauv qhov cub.

Kub ntawm950℃rau 90 feeb.

Tshem tawm, txias rau chav sov, thiab sau qhov hnyav ntxiv liG4, uas sawv cev rau cov ntsiab lus tshauv.

---

Final Graphite Powder Purity Calculation

Siv cov ntsuas ntsuas, graphite hmoov purity yog xam raws li:

C (%) = [(G2 − V − G4) / G2] × 100%

Qhov tshwm sim no sawv cev rauruaj cov ntsiab lus carbon, uas txhais cov purity qib ntawm graphite hmoov.

Qhov tseem ceeb ntawm Purity Testing rau siab -Purity Graphite hmoov

Graphite hmoov purity tshwj xeeb tshaj yog tseem ceeb rausiab -purity thiab siab - carbon graphite cov khoom. Tsuas yog cov ntaub ntawv uas ua tau raws li qhov yuav tsum tau ua ntawm cov pa roj carbon monoxide yuav raug txiav txim siabcov khoom tsim nyograu siab - cov ntawv thov kawg xws li:

Lithium{0}} cov khoom siv roj teeb

Nuclear - qib graphite

Advanced carbon cov ntaub ntawv

Precision industrial Cheebtsam

Kev ntsuas purity nruj kom ntseeg tauzoo ib yam, kev cia siab rau kev ua tau zoo, thiab kev nyab xeeb ntawm daim ntawv thov.
